A method of and apparatus for cleaning a surface, such as a wall of a waste boiler of a Kivcet furnace, are described. The invention comprises suspending a pair of spaced apart cables adjacent a surface to be cleaned, attaching ends of the rail to respective ones of the cables with equal lengths of cable between the rail and the roof, the rail being reversibly moveable up and down the surface. A carriage has a nozzle assembly, operative to emit a jet of water, with the carriage reversibly moveable along the rail. The rail is moved from one of a top and bottom of the surface to another of the top and bottom of the surface, and the carriage is moved from one side of the rail to another, cleaning the surface as it moves. The foregoing steps are repeated for each remaining uncleaned surface. |
